To automate the task of assigning a fixture for the test case, for test case creation use the macro
|
||
BOOST_FIXTURE_TEST_CASE in place of the macro <code class="computeroutput"><a class="link" href="../test-organization/auto-nullary-test-case.html#BOOST_AUTO_TEST_CASE">BOOST_AUTO_TEST_CASE</a></code>:

<p class="first-line-indented">
|
||
The only difference from the macro <code class="computeroutput"><a class="link" href="../test-organization/auto-nullary-test-case.html#BOOST_AUTO_TEST_CASE">BOOST_AUTO_TEST_CASE</a></code> is the presence of an extra argument
|
||
- fixture name. Unlike the pure C++ solution you have direct access to the public and protected members of the
|
||
fixture, though you still need to refer to the fixture name in every test case.

what can be done if all test cases in a test suite require the same fixture.
